Need some help from Hardcore Madlib Fans

I'm currently putting together a list of all of Madlib's releases (under all aliases of course) for personal use, and i'm almost finished. I was just wondering if the knowledgeable users here could help me out by telling me which of his EP's contains original music that isn't later used on full length LP's. Dude has so many ep's and singles that it's making my head spin, trying to figure out what is what is proving somewhat difficult. Also it doesn't matter if it's digital or wax only.

Was YNQ's version of 'Harlem River Drive' ever released as a 45? I figured it was only because it is on that PBW comp. I know Lib threw it on MMS#1 with Dilla vibing over it for a few seconcds, but I'm curious to know if it has seen its own release.
